Many Thanks to all that responded to my
request for info on concrete curing time.
I have had some nights below freezing, which
slows the curing time. So I will wait the 28 days
just to be sure. Unfortunately that will put me out
of the CQWW CW for this year but wait till next year!!!
Thanks again and 73, Ted K2QMF
